**************************ENGLISH VERSION*********************
The International Space Station (ISS) is the greatest artificial satellite ever built by Humans. Thanks to a 2 500 m² solar panel area, the dimension of the ISS is nearly the same as a soccer field.
So, when these numerous solar cells receive the sunlight, a huge part of this light can be directly reflected towards us. Therefore the space station is often visible from the Earth and to the naked eye !

• The ISS : a bright point moving in the night-sky •

When the solar pannel's orientation and the Sun's illumination are good enough, the space station appears as a shining point evolving across the sky, faster than a jetplane, and sometimes as bright as a planet.

If you see it for the first time, it seems difficult to trust the person who told you that. It is absolutely understandable because we actually do not see the shape of the ISS as we know it.

To check this out, capturing the station with a telescope is the only solution.

• ISS telescope photography : a real challenge •

Imagine a soccer field located at 400 km away from you, travelling at 28 000 km/h so that in a second lapse of time, this objet has already travelled roughly twice the Moon's diameter !
Plus, the trajectory of the station continously evolves. For example, the elevation never remains the same at each sighting.
You finally understand that following this fast object using a powerful-magnification telescope is considered as a real challenge !

★ Nagy Szabolcs, a London-based amateur astronomer lately decided to take-up this challenge. Equipped with a Dobson 250/1200 mm telescope with a x 2 barlow lens, and a CCD camera, Nagy managed to capture the ISS on december 11 and december 14 2016, without using any tracking mount.

On december, 13 2016, the latest supplying vehicle had docked to the station : the HTV-6 Japanese cargo. Indeed, the Image n°1 shows the difference between both of those dates : before and after the vehicle was attached.

The outcome of his work is tremendously mindblowing ! Images reveal an impressive detail of the station 's structure. The famous robotic arm Canadarm2 is even visible.

Image n°3 above is a color version of the Nagy Szabolcs's image. What an amazing view !

For further details of the Nagy's ISS sighting, I let you to watch this video he made for us :
